You will have to determine where leak is from. It would be dip stick tube, trans lines, pan gasket, or the main wiring plug to the trans. Also clean and check the cover between motor/trans and see if it is comming out of a hloe in cover.

To fix you will have to determine exactly where it is comming from. You may have to pull the heat sheid off. It is a 13mm and only 2 bolts.
